So your saying that if the L cant cut it at 1.2 it will be better at 1.4 ??? Maybe you would like to explain. How much better can the test be then same camera, same place, same time of day and max aperture for all 4.

Of course, since the sigma can't even do 1.2

I have little doubt the sigma is a bit sharper overall,

but as I said, it's a totally meaningless exercise, in my opinion,

to compare them at different apertures.

Scroll up this thread to see images of the two compared at the same apertures. In those instances, individuals complained that they were not compared wide open. The sigma simply is better and costs less. Both wide open and at the same apertures.
